TILE-CUTTING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 661,625, dated November 13, 1900.

Application filed July 31, 1900. Serial No. 25,415. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE A. STANBERY, a citizen of the United States, and a resident of Zanesville, Muskingum county, State of Ohio,

have invented certain new and useful Improvements in Tile- Cutting Machines, of which the following is a specification.

This invention relates to a machine for cutting up a tile-bar, such as illustrated in Figures 8 and 12, into a number of smaller tiles. These tiles may either be rectangular, Fig. 12, or they may be trapezoidal-4;. e., with two parallel and two equally-inclined sides, Fig. 9.

With the more complex form of the ma- I 5 chine, which is illustrated in Figs. 1 to 7, rectangular, as well as trapezoidal, tiles are cut, the machine being so constructedthat the length of the tiles and alsothe degree of divergence of their sides may be readily adjusted.

With the more simple form of the machine, which is illustrated in Figs. 10 and 11, rectangular tiles only can be out; but here, too, the length of the tile is adjustable.

In the accompanying drawings, Fig. 1 is a plan, partly in section, of my improved tilecutting machine; Fig. 2, a side elevation thereof; Fig. 3, a vertical cross-section on line 3 3, Fig. 1. Figs. 4 and 5 are similar sections on line 44, Fig. 1, showing the parts in difierent positions; Fig. 6, a similar section on line 6 6, Fig. 1; Fig. 7, a detail of the rest-actuating mechanism. Fig. 8 illustrates atile-bar with its lower part severed by the machine to constitute a trapezoidal tile. Fig. 9 illustrates several of such tiles arranged to form a pattern. Fig. 10 is a plan of a modification of the machine; Fig. 11, a sectional. elevation on line 11 11, Fig. 10; and Fig. 12 illustrates a 4o tile-bar with a rectangular tile severed thereand a feather m in shank m These cutters are arranged in alinement with each other on opposite sides of the guide Z) and in a plane between such guide and the rest 0, the guide and rest being in turn arranged in a vertical plane between the cutters. The cutters d e are adj ustably secured to the rock-shafts f g, respectively, of which the rear shaft f is adapted to receive a rocking motion only, while the front shaft g is adapted to receive a longitudinally-reciprocating as well as a rocking motion. The shafts f g oscillate in the bearings f g, respectively, and are so coupled to each other that they will rock in unison and that thus the cutting edges of the front and rear cutters are always in alinement.

The mechanism for imparting the rocking motion to the shafts f and g is as follows: h, Fig. 3, is the main shaft, driven by hand or power and turning in bearings h of frame a. The shaft it rotates a counter-shaftt' by miterwheels b 11, and the shaft t in turn rotates by bevel-wheels 11 j a longitudinal shaft j, turning in bearings 7' The proportion of pitch diameters between the wheels 2' andj is as one to two, so that for a complete rotation of shaft h a semirotation of shaft is obtained. The shaft j carries a crank-disk k, Figs. 1, 4, and 5, having a diametrical or radial groove 70', which is engaged bythe crankpin Z of a connecting-rod Z. The crank-pin Z is adapted to be adjusted Within the groove is at any desired distance from the center, so as thereby to change the stroke of rod Z. The upper end of rod Z loosely embraces the crossbar m of a yoke adapted to be oscillated by the rod and having a pair of shanks m and m The rear shank m is rigidly connected to the rear rock-shaft f,.while the front shank m loosely embraces the front rock-shaft g, to which it is coupled by a groove 9 of shaft 9 In this way the yoke is adapted to simultaneously rock both shafts fg, while at the same time the shaft g is free to reciprocate longitudinally, so as to move the cutter 6 toward and away from the cutter d. This longitudinal movement is imparted to the shaft 9 by an eccentric n, Fig. 3, mounted on shaft h and embraced by a strap n, into which is tapped a rod 71?. This rod is coupled to shaft g by a ball-and-socket joint 01 41 By unscrewing the rod n -more or less and tightening up a jam-nut n a longitudinal adjustment of shaft g may be effected to compensate for size and wear of the cutters.

The tile-rest c is so constructed that it will descend after every cut and rise before the next cut is made, so as to support the tile dispensed with; but the reciprocating mo tion of the shaft 9 and also of the support 0 is retained and effected in the manner above described. Thus a rectangular tile is severed at each stroke of the cutter and is then discharged by the lowering of the support.

What I claim is 1. In a tile-cutting machine-the combinawhile being severed and to freelydischarge the detached tile and prevent jamming.

The construction for carrying this result into effect is as follows: Upon the shaft his mounted a cam or nose 0, which in conjunc-- tion with a spring 0' reciprocates a rod 0 To this rod is connected a slide 19, having a lower inclined surface p, Fig. 7. This surface engages a pin q, Fig. 6, which rests upon the flange of an adjusting-nut r. Through this nut is tapped the threaded and reduced stem 0 of rest 0, surrounded by a spring a and carrying a winged jam-nut 0 By loosening the jam-nut c and setting the nutthe elevation of rest 0 may be adjusted to out longer or shorter tiles. When the slide 19 moves backward, its incline p will depress rod q and lower rest cagainst action of spring 0 When the slide 10 retracts, Fig. 7, the rest a, as well as rod q, will be raised by spring 0 to their upper terminal position.

The operation is as follows: Motion being imparted to the machine, the tile-bars A are successively fed into the guide I) so as to rest upon support 0. By means of the yoke m m m the shafts f g are rocked in unison, while the shaft 9 is furthermore reciprocated axially by means of eccentric n. Thus the cutters are rocked and at the same time alternately opened and closed against each other, each double rotation of shaft h causing two complete strokes of cutter e and a complete to-and-fro rocking motion of both cutters d and 6. Thus the tile-bar A will be out alternately on the right and left sides of the axis of the rock-shafts, each pair of successive cuts tapering equally in opposite directions, so that each tile severed (with the exception 'of the end tiles) will have a trapezoidal face with two parallel and two evenlydiverging sides, Figs. 8 and 9. As soon as a tile has been severed the rest 0 will descend to permit the tile to drop into a suitable receptacle and will then rise ready for the next cut. The taper of the tiles may be readily varied by setting the crankpin Zmore or less toward the center of disk It. When the centers of crank-pin Z and disk is coincide, no rocking motion whatever of the shafts f 9 will take place, and consequently rectangular tiles, such as shown in Fig. 12, will be severed.

To set the machine to any degree of taper desired, the rod Z is provided with a scale Z which is brought opposite to a pointer Z when the rod is in a vertical position, Fig. 5.

In Figs. 10 and 11 a simplified form of the machine is shown, which is adapted to cut rectangular tiles only. Here the rocking motion of the cutter-carrying shafts is entirely port, means for imparting a reciprocating movement to said support, and means for adjusting the elevation of said support, substantially as specified.

3. In a tile-cutting machine, the combination of atile-guide, withatile-support, means for imparting a reciprocating movement to said support, and a pair of cutters arranged in a plane intermediate between the tileguide and the tile-support, substantially as specified.

4. In a tile-cutting machine, atile-support composed of a vertically-movable spring-actuated rest combined with a pin for lowering the same, and a slide having an inclined face that engages said pin, substantially as specified. Y

5. In a tile-cutting machine, the combination of a tile-support composed of a vertically-movable spring-actuated rest with a nut engaging the same, a pin supported upon the nut, and a slide having an inclined face that engages the pin, substantially as specified.

6. In a tile-cutting machine, the combination of a tile-guide, with a rock-shaft, a cutter secured thereto, and means forimparting reciprocating axial movement to the rockshaft, substantially as specified.

7. In a tile-cutting machine, the combination of a tile-guide, with apair of rock-shafts, cutters secured thereto, means for oscillating said shafts in unison, and means for reciprocating axially one of said shafts, substantially as specified.

8. In a tile-cutting machine, the combination of a pair of rock-shafts, with means for oscillating said shafts in unison, means for reciprocating one of said shafts, and a vertically-movable rest for supporting the severed tile, substantially as specified.

9. In a tile-cutting machine, the combination of a tile-guide, with a vertically-movable tile-support, a pair of rock-shafts arranged in a plane intermediate between the guide and support, means for oscillating said shafts, and means for reciprocating axially one of said shafts, substantially as specified.

10. In a tile-cutting machine, thecombination of a tile-guide, with a vertically-movable tile-support, a pair of rock-shafts, arranged in a plane intermediate between the guide and support, means for adjusting the oscillation of said shafts, and means for reciprocating axially one of said shafts, substantially as specified.

11. In a tile-cutting machine, the combination of a yoke, with means for oscillating the same, a pair of shafts adapted to be rocked by the yoke, and a sliding connection between one of said shafts and the yoke, substantially as specified.

12. In a tile-cutting machine, the combination of a crank-disk, with a rod adjustably coupled thereto, a yoke operated by the rod, a pair of shafts adapted to be rocked by the yoke, and a sliding connection between one of said shafts and the yoke, substantially as specified.

13. Ina tile-cutting machine, the combina tion of a pair of rock-shafts, with means for rocking said shafts in unison, means for adj usting the lateral movement of the shafts,
